Factor X deficiency results in a rare but serious bleeding disorder that might be treated by expressing a normal factor X gene in patients. We generated an amphotropic retroviral vector with the human FX cDNA and delivered it to rat hepatocytes in vivo during liver regeneration. The human alpha1-antitrypsin promoter was chosen to direct expression because(More)
BACKGROUND To determine whether prophylactic placement of an inferior vena cava (IVC) filter in bariatric patients deemed to be at high risk is effective in reducing their risk of pulmonary embolism. The study was performed at a bariatric center in a community hospital. METHODS This was a retrospective study of all patients in the Hurley Bariatric Center(More)
There are no guidelines to determine when bronchoscopy is appropriate in patients with inhalation injury complicated by pneumonia. We reviewed the National Burn Repository from 1998 to 2007 to determine if there is any difference in outcome in burn patients with inhalation injury and pneumonia who did and did not undergo bronchoscopy. Three hundred(More)
BACKGROUND There is almost no data describing the long-term functional outcome of patients after penetrating cardiac injury. METHODS A retrospective study at a Level I trauma center from 2000 to 2009. RESULTS Sixty-three patients had penetrating cardiac injuries from 28 stabbings and 35 gunshots. Men comprised 89% (56) of the patients. Overall, there(More)
Hepatic gene therapy might correct the clinical manifestations of several genetic disorders in patients. Although retroviral vectors with a strong liver-specific promoter can result in stable and therapeutic levels of expression of genes from the liver, application of these techniques in humans is limited by the need to perform one or more invasive(More)
Hepatic gene therapy could improve the treatment of many inherited disorders. Although retroviral vectors result in long-term expression in hepatocytes in vivo, their low level of expression currently precludes most clinical applications. Four copies of the liver-specific apolipoprotein E (ApoE) enhancer were placed upstream of the human alpha 1-antitrypsin(More)
Protein C deficiency results in a thrombotic disorder that might be treated by expressing a normal human protein C (hPC) gene in patients. An amphotropic retroviral vector with a liver-specific promoter and the hPC cDNA was delivered to rat hepatocytes in vivo during liver regeneration. Expression of hPC varied from 55 to 203 ng/ml (1.3-5.0% of normal) for(More)
Activated macrophages are important cell effectors in sepsis/endotoxemia. Superoxide (SO) and nitric oxide (NO) are produced by activated macrophages and are responsible for host defense against microorganisms. Using laser scanning confocal microscopy, we investigated the role of intracellular free calcium ([Ca2+]i) on SO and NO production by rat peritoneal(More)
The cell of origin of hepatocellular carcinoma (HCC) is controversial. A method for marking cells of different lineages in vivo and then determining their carcinogenic potential should resolve this issue. A retroviral vector expressing activated ras and beta-gal genes (Ras-gal) was transferred into adult rat hepatocytes in vivo, and some animals were(More)
Although the molecular signaling mechanisms underlying macrophage endotoxin (LPS) responsiveness are not fully understood, alterations in intracellular phosphatidylinositol (PI) metabolism appear to contribute. We evaluated the effects of endotoxin tolerance (ET) induction upon peritoneal macrophage (PM) expression of the principal PI enzymes phospholipase(More)
